/**
   Macro for converting DDL (digit) files into HLT RawData. 
   In "inpath" expected are the ddl files (called Ev0TPCslice 
   followed by number), the compressed HLT files will be
   in "outpath", and can be used as the input to the tracker.
   Singlepatch uses one file per slice (sp=kTRUE) (which 
   is probably what we want if we run it on the GDCs)

   Note: event is not used yet.
